SPECIFICATION forming part of Letters Patent No. 731,012, dated J' une16, 1903. Application filed August 11, 1902. Serial No. 119,325. (Nomodel.)

To all whom it may concern:

Be it known that I, FRANK AVERY, a citizen of the United States,residing at Orin, in the county of Conversel and State of l/Vyoming,have invented a new and' useful BedlVarmer, of vwhich the following is aspecification. Y c

My invention is an improved bed-warmer adapted for use for heating bedsand for other purposes; and it consists in the peculiar construction andcombination of devices hereinafter fully set forth and claimed.

In the accompanying drawings, Figure 1 is an elevation, partly insection, of a bedwarmer embodying my improvements. Fig. 2 is a similarview showing a modiied construction thereof. 4

In theembodiment of my invention here shown the same is applied to anoil heatingstove, of which 1 designates the font or lamp forming thebase, and 2 the radiating-drum, which is disposed on 4the upper sidethereof and is hinged thereto, as at 3. On the side opposite the saidhinge there is a catch 4 to secure the radiating-drum in a closedposition on the font or base. In the radiating-drum is an air-heatingelement, which in the form of the invention shown in Fig. 1 is anannular chamber 5, formed on the inner side of the radiating-drum 2 by adrum 6, which is spaced therefrom. In the form of my invention shown inFig. 2 the air-heating element is formed by a coil of pipe 7, disposedon the inner side of the radiating-drum. Within the scope of myinvention the air-heating element may be of any suitable construction,

and I do not desire to limit myself in this particular. air-heatingelement and from any suitable means for forcing cold air into theair-heating element through the said feed-pipe S. A

bellows 9 is here shown for this purpose; but

a suitable air-pump may be employed in stead of the bellows, ifpreferred, and I do not limit myself in this particular. .The bellows ishere shown as disposed `under the font or lamp 1 between thesupporting-legs 10. In the connection between the bellows and theair-feed pipe S is a check-valve 11.

feed pipe includes a lower section 8, which is fixed with relation tothe base of the stove or heater, and "an upper section 8b, which is Anair-feed pipe S leads to the The airfixed withrelation to the hingeddrum 2 and Vdetachably jointed to the lower section 8, as

at 8C. This air-feed pipe connects with the lower portion of theair-heating chamber 5 or with the lower end of the coil 7.

At the upper side of the air-heating'chamber 5 or at the upper end ofthe coil 7 as the case may be, is a nipple 12, which leads therefrom andin which is a valve 13 to control the escape of heated air from theair-heating element. A spring 14 is here shown which normally closes thesaid valve 13 and the tension of which is such as to cause the air to becompressed in the air-heating element before it can escape therefrom,thus retaining the air in the air-heating element a sufficient length oftime to cause it to become thoroughly heated. A flexible conducting-pipe15 leads from the nipple 12 and is of sufcient length.

In the operation of my invention the air heating chamber or pipe coil isfilled with air, compressed therein by operating the bellows 9, andbecomes heated, as will be understood. By means of the flexibleconducting-pipe l5 the heated air may be applied to the bed and betweenthe covers to comfortably warmthe bed before it is used.

There my improved bed warming apparatus is applied to an oil-stove, ashere shown,

the same is not inconsistent with the use of the oil-stove for ordinaryheating purposes. Having thus described my invention, I claim- -A stovehaving a radiating-drum, hinged thereto, an air-heating element in saiddrum,

'a feedpipecomprising a section, xed to a fixed portion of the stove,and a section carried by the hinged drum and communicating with theair-heating element, said sections being adapted to connect anddisconnect, means to force air into the air-heating element through thesaid feed-pipe, and a hotair conductor leading from the air-heatingelement, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afixedmy signature in the presence of two witnesses.

FRANK AVERY.
